We study the number of flux vacua for type IIB string theory on an orientifold of the Calabi-Yau expressed as a hypersurface in WCP 4 [1, 1, 2, 2, 6] by evaluating a suitable integral over the complex-structure moduli space as per the conjecture of Douglas and Ashok. We show that away from the singular conifold locus, one gets a power law, and that the (neighborhood) of the conifold locus indee...

The ability to make decisions and to assess po­ tential courses of action is a comer-stone of many AI applications, and usually this requires explicit information about the decision-maker's prefer­ ences. In many applications, preference elic­ itation is a serious bottleneck. The user ei­ ther does not have the time, the knowledge, or the expert support required to specify complex multi-attribu...

Two major degradations, edge displacement and comer erosion, change the appearance of bilevel images. The displacement of an edge determines stroke width, and the erosion ofa comer affects crispness. These degradations are functions of the system parameters: the point spread function (PSF) width and functional form, and the binarization threshold. Changing each of these parameters will affect a...

The primary aim of this paper is to illustrate the value of visualization in cartography and to indicate that tools for the generation and manipulation of realistic images are of limited value within this application. This paper demonstrates the value of visualization within one problem in cartography, namely the generalisation of lines. It reports on the evaluation of the Douglas-Peucker algor...

Proper relation algebras can be constructed using Z/pZ as a base set using a method due to Comer. The cycle structure of such an algebra must, in general, be determined a posteriori, normally with the aid of a computer. In this paper, we give an improved algorithm for checking the cycle structure that reduces the time complexity from O(p) to O(p).
